SASS mixin to generate breakpoints for a given style
// Breakpoint Variables
$xs-break: em(400px);
$sm-break: em(600px);
$md-break: em(800px);
$lg-break: em(1000px);
$xl-break: em(1200px);
// Size Suffixes
$xs-suffix: "-xs";
$sm-suffix: "-sm";

This solution does not actually work, but is extremely close (one character off) from efficiently generating breakpoints with more control than version 1.
// Breakpoint Variables
$xs-break: em(400px);
$sm-break: em(600px);
$md-break: em(800px);
$lg-break: em(1000px);
$xl-break: em(1200px);
// Size Suffixes
$xs-suffix: "-xs";
$sm-suffix: "-sm";
